Refer to the Vista Section of this Help Site for details on the use of this module; however, the following is typical:
Carry out common sense simulation checks:
· Occupancy & gains operate at the desired times (line chart & table);
· Set-points are correct at the desired times (line chart & table);
· Auxiliary ventilation (NVHR supply fan) operates at the desired times (line chart & table);
· Openings operate at the desired times (line chart & table);
· Room temperature conditions do not lie outside of sensible limits (line chart & table);
· Room CO2 conditions do not lie outside of sensible limits (line chart & table).
It is important that an appropriate number of NVHR rooms are assigned to a space; an insufficient number of units can often be detected by poor CO2 performance.
Carry out design performance checks:
· Winter temperature test (range test < X°C (e.g. 20°C), occupied hours, heat map);
· Summer low-level overheating test (range test > X°C (e.g. 23°C), occupied hours, heat map);
· Summer comfort overheating test (range test > X°C (e.g. 25, 28°C), occupied hours, heat map);
· CO2 test (range test > X PPM (e.g. 1000 PPM), occupied hours, heat map);
· Room temperature both when occupied and during night cool (line chart);
· Operation of mechanical cooling if provided versus room temperature (line chart);
· Active opening operation versus internal & external temperatures (line chart & table);
· Energy use (line chart & summary table).
It is important that you review simulated operation and consider adjusting NVHR set-point values to fine tune the design performance.
Carry out compliance performance checks:
